Australia, the United Kingdom, and the United States entered into a trilateral security partnership called AUKUS to build nuclear-powered submarines for the Royal Australian Navy
SSN-AUKUS Submarine: For the Royal Australian Navy, 3 Western countries Australia, the United Kingdom, and the United States entered into a trilateral security partnership for the construction of a nuclear-powered submarine. Under the SSN-AUKUS program, Australia’s ASC and UK-based BAE Systems will collaborate to build the submarines, where the vessels will be based on a British design but will incorporate a US weapons system. Australia will provide 4.6 billion Australian dollars ($3 billion) to the British industry to support the construction of the SSN-AUKUS submarines and ensure the timely delivery of the new fleet.

The SSN-AUKUS (SSN-A) is a planned class of nuclear-powered fleet submarines set to replace the UK’s Astute class and Australia’s Collins class submarines. Development began in 2018 as the Submersible Ship Nuclear Replacement (SSNR) project, renamed SSN-AUKUS in 2023 with Australia’s involvement in the AUKUS partnership. Rolls-Royce’s pressurized water reactors (PWR) will power the submarines, with construction to occur in the UK and Australia. They will feature advanced sensors and armaments. Service is anticipated to start in the late 2030s for the UK and early 2040s for Australia.
